One second, the world was full. The next, she was the only one left. Nineteen-year-old Wren lives a quiet life-introverted, soft-spoken, and rarely seen outside her small home. But when the entire population of Earth disappears in the blink of an eye, Wren is forced into a silence deeper than she ever imagined. Alone in a world that no longer breathes, she must learn how to survive without power, without people, without a plan. From forgotten libraries to overgrown cities, she pieces together a life in the ruins of the old one. But as the seasons change, Wren begins to realize that survival is only half the story-and loneliness is its own kind of danger. What do you do when the world falls asleep... and you're the only one still awake? A haunting, tender exploration of grief, isolation, and the quiet courage it takes to rebuild, When the World Slept is a story of endings, beginnings, and the strange, beautiful places we find hope.
